ANOTHER GREAT STEP

BREAKTHROUGH STAR SHOT

If we wish to travel at higher speeds through interstellar space, we must to bring our
technology to the benchmark for excellence: the speed of light. Based on the previous,
Stephen Hawking perfected the idea of ​​Carl Sagan (boosting spacecraft with
solar wind), to send into space an extremely light miniprobe, driven by thousands of laser rays emitted by an array of
emitting laser light dispositives settled in land with a 100-gigawatt power in
order to achieve the solar system closest
to our: Alpha Centauri (distant :4.3
light years from our solar system). While arriving at the edge of this
tri-solar system with current technology, would take 30.000 years, according to
the Russian billionaire Yuri Millner materialize the idea-project of Hawking: Breakthrough Star Shot, would permit to
arrive to Alpha
Centauri in only 20 years. For Pete Worden former NASA scientist, Head of the Project Breakthrough Star Shot, photon recoil would
accelerate the speed of the miniprobe to ¼ or 1/5 of the speed of light, in 2
minutes, bringing this nano- ultralight craft (6 g total weight, containing 1 g
starchip camera, laser communications, computer, nuclear battery, sensors, and
others), to Mars in 30 minutes and to Pluto
in 3 days. According to Philip Lubin (University of California, Santa Barbara),
while current rockets traveling under the principle of repulsion, eject gases,
many probes and satellites use ion power as propellants. The miniprobes of
Hawking, would use photons as propellants. These miniprobes would be transported
with rockets into Earth orbit, where after spread its wings would be launched
into space using lasers as propellants.
